Can I trust my back-up?

I see that no one has bothered to reply yet.
I have an earlier version of TI than yours so what I have to say may or may not help.
I noticed from the image you attached that the calendar entries for days 28 July to 10 August appear to be coloured red.
Does this mean that the backup or incremental backup for those days failed.
With my version of TI, 11 Home, the restore process gives an opportunity to check the backup before proceeding to do the restore.
Maybe your TI Home 2010 will do the same once you start the backup process but do not continue to commit to do it.
If the check of the backup fails you may not want to trust your current backups.
I suggest that you may want to clear the TI log and delete any full and incremental backups if that is possible with your version and start again by initially making a full backup.

Edit: The TI backups on my external hard drive have file type .tib

Hi welsmike, thank you very much for your answer! I already cleared the daily schedule and made a new one but that did not solve the problem. My backups also have the .tib extension. As far as I can see the check in the restore procedure is not available in home 2010.

From other discussions here I suspect that the two proceeding failure messages probably are the result of TI trying to login in Windows XP without having a password, as I don't use a password to login in my PC.

However, all the resulting red blocks in my calendar and the two failure messages in my daily log would not bother me as long as I can rely on the backup that in spite of this error messages is made. If the backup is correct I don't see the sence of scaring people that somewhere in the process there was a failure. So I would appreciate if a TI official could tell me if I don't have to fear for corrupt backups.

Jan,

Don't rely on luck, you should prove your restoration process now, before you actually need it.

A few suggestions: Get all of your user data off of the system (C) partition, including e-mail. Do a web search on migrating your e-mail to a different partition, its easy. With no user data on the system partition, you don't have to back it up very often because it changes infrequently. You can just run a manual backup every couple weeks or so instead of scheduling it daily. This greatly simplifies the whole process, reducing the probability of things going wrong, and makes the system partition backup files smaller as well.

Next you must validate your backup file(s), which is a simple process as well, pull down the menus and you'll find it if you haven't already done this.

The final step is to put in the recovery boot CD and try to restore your system partition from the backup. The best test is to do this to a spare drive, but second best is to follow the menu all the way to the final step where you are asked to hit the 'proceed' button, and just hit 'cancel' instead.

And one should ALWAYS validate any disk image backup from bootable media, since this is where restoring will take place from. Validation in Windows is not good enough and can be misleading, since the environment is different.
